Ok so you have to REALLY HURRY to win!!
When I see my country's flag, I see peace and unity.
Basically talk about how seeing your country's flag makes you feel safe that your country is peaceful and how everyone is friendly and united. You should expand on the idea of your country being peaceful, like for example, if your country hasn't been in war, talk about how you feel safe because of that. Expand on the idea of unity.
I really hope this helped and best of luck you you!! :)
